Japanese Patent No. 3917083 JP 2002-130062 JP 2001-65416 A JP 2002-70662 A JP 2002-242769 A

  In addition to improving the combustibility obtained by each of the above-described configurations, in the combustion chamber of an internal combustion engine or boiler combustion furnace, etc., not only simply improving the combustibility but also improving the combustibility, the integrated total in the combustion process There is a need for improvement in energy efficiency.

  SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to solve the above-described conventional problems and improve energy efficiency as well as combustibility in a combustion chamber such as an internal combustion engine or a boiler combustion furnace.

  The present invention improves the combustibility in the combustion chamber by increasing the temperature of the combustion air in the magnetic treatment of the combustion air supplied to the combustion chamber. The present invention improves energy efficiency by utilizing the exhaust heat exhausted from the combustion chamber in the configuration for raising the temperature of the combustion air. In the magnetic treatment, the combustion efficiency is improved by circulating the combustion air in the magnetic field, thereby improving the combustibility.

  The combustion improving apparatus of the present invention performs heat exchange between a combustion chamber for burning fuel, an exhaust gas exhausted from the combustion chamber, and combustion air supplied to the combustion chamber, and supplies the combustion air to the combustion chamber And a magnetic processing chamber for passing combustion air heated by the heat exchanger into a magnetic field.

  Combustion air is air used for fuel combustion in the combustion chamber. Here, in addition to the air taken into the combustion improving apparatus, it also refers to the air in the outside air before being taken into the combustion improving apparatus.

  The combustion chamber is a mechanism that burns together with liquid fuel such as heavy oil, kerosene, light oil, gasoline, and combustion air in an internal combustion engine, boiler combustion furnace, and the like, and converts it into heat energy and kinetic energy. Here, in the case of an internal combustion engine, the combustion chamber includes an injection device that mixes the engine portion, liquid fuel, and combustion air and feeds the mixture into the engine. The boiler combustion furnace includes a burner that burns a mixture of liquid fuel and combustion air, and a boiler that heats a heat medium such as water by the heat of the burner.

  The heat exchanger has a shape having an inner tube and an outer tube constituting a double tube. The inner pipe allows exhaust gas from the combustion chamber to pass through. The outer tube forms an annular space between the inner wall and the outer wall of the inner tube, and the first and second intake ports for taking combustion air into the annular space, and the combustion air in the annular space. It has a spiral wall surface that forms a spiral passage, and an exhaust port that exhausts the captured combustion air.

  The first intake port takes combustion air into the spiral passage from the outside air side at the start end side of the spiral passage. The taken-in combustion air is heated by the heat of the exhaust gas passing through the inner pipe while passing through the spiral passage. By making the passage into a spiral shape, it is possible to increase the efficiency of heat exchange from the exhaust gas to the combustion air by extending the length that the combustion air contacts the outer wall of the inner tube.

  The second intake port takes combustion air from the outside air into the annular space and adjusts the temperature of the heated combustion air. The second air inlet is provided on the downstream side of the first air inlet in the spiral passage, and may be provided in an intermediate portion other than the lower end of the spiral passage.

  The combustion air taken in from the second intake port is at a lower temperature than the combustion air heated while passing through the spiral passage, so that the temperature of the heated combustion air is lowered to adjust the temperature. .

  The exhaust port sends the temperature-adjusted combustion air to the magnetic processing chamber. The magnetic processing chamber passes the combustion air supplied from the heat exchanger into the magnetic field and then supplies the combustion air to the combustion chamber.

  The heat exchanger can improve energy efficiency by heating the combustion air using waste heat contained in the exhaust gas from the combustion chamber.

  In the heat exchanger of the present invention, the second intake port has an open / close shutter that allows the opening area to be freely changed, and this open / close shutter constitutes a temperature adjustment mechanism. The temperature adjustment mechanism changes the volume of combustion air taken into the annular space from the outside air side, and adjusts the temperature of the heated combustion air. When the opening degree of the open / close shutter is increased, the volume of the combustion air taken into the annular space is increased, and the amount of decrease in the temperature of the heated combustion air is increased. On the other hand, when the opening degree of the open / close shutter is reduced, the volume of the combustion air taken into the annular space is reduced, and the amount of decrease in the temperature of the heated combustion air is reduced.

  In addition, the temperature adjustment mechanism of the present invention may have a drive mechanism that drives the open / close shutter. The drive mechanism can adjust the open / close amount of the open / close shutter based on the temperature information fed back from the heat exchanger or the magnetic processing chamber, thereby adjusting the temperature of the combustion air to a predetermined temperature.

  The magnetic processing chamber of the present invention is configured with a plurality of magnetic processing members that allow combustion air to pass therethrough. The magnetic processing member includes a permanent magnet disposed in the axial center, a cylindrical housing that extends around the axial direction with a gap between the permanent magnet, and an axial direction in the gap between the permanent magnet and the housing. And a helical wire provided in the above. The housing provided in the magnetic processing chamber of the present invention has an opening through which combustion air can pass freely inside and outside the housing.

  In the cylindrical housing, a magnetic field is formed by a permanent magnet arranged at the axial center, and the combustion air passing through the housing is magnetized. On the other hand, in the configuration in which the cylindrical housing of the magnetic processing member is provided, a space where no magnetic field is formed is formed between adjacent housings. The combustion air passing between the housings is not magnetized.

  The opening provided in the housing of the present invention can be magnetized by allowing combustion air passing outside the housing to be taken into the housing by communicating the inside and outside of the housing. Thereby, the efficiency of the magnetization process of the combustion air can be improved.

  The magnetic processing chamber of the present invention includes an air return path for returning a part of the magnetically processed combustion air to the inlet side. This air return path allows the combustion air to pass through the magnetic field multiple times. Thereby, the efficiency of the magnetization process of the combustion air can be improved.

  In the magnetic processing chamber of the present invention, a plurality of constituent members provided with a plurality of magnetic processing members are arranged at intervals along the flow direction of the combustion air so as to form an air pocket with an interval between the constituent members. It can be set as the structure to do. In the flow path of the combustion air in the magnetic processing chamber, an air pool is formed between the constituent members that perform the magnetization process, so that the combustion air that has been magnetized and the combustion air that has not been magnetized And the magnetization process can be performed again. Thereby, the ratio of the combustion air that has not been magnetized can be reduced, and the efficiency of the magnetization process of the combustion air can be improved.

  ADVANTAGE OF THE INVENTION According to this invention, the combustibility in combustion chambers, such as an internal combustion engine and a combustion furnace of a boiler, can be improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 and 2 are diagrams for explaining a schematic configuration of a combustion improving apparatus 1 according to the present invention. FIG. 2 shows a configuration example in which the adjustment of the intake amount of combustion air is automatically performed.

  In FIG. 1, a combustion improving apparatus 1 according to the present invention performs heat exchange between a combustion chamber 2 for burning fuel, an exhaust gas exhausted from the combustion chamber 2 and combustion air supplied to the combustion chamber 2, A heat exchanger 3 for heating combustion air supplied to the combustion chamber 2 and a magnetic processing chamber 4 for passing the combustion air heated by the heat exchanger 3 into a magnetic field are provided.

  The combustion chamber 2 is a mechanism that burns with liquid fuel such as heavy oil, kerosene, light oil, and gasoline and combustion air in an internal combustion engine, a boiler combustion furnace, and the like, and converts it into heat energy and kinetic energy. In the case of an internal combustion engine, it includes an engine 2a and an injection device 2b that mixes liquid fuel and combustion air and feeds the mixture into the engine 2a. Further, in the case of a boiler combustion furnace, it is configured to include a burner 2d for burning a mixture of liquid fuel and combustion air, and a boiler 2c for heating a heat medium such as water by the heat of the burner 2d. it can. The exhaust gas after combustion in the combustion chamber 2 is exhausted from the exhaust pipe 6.

  The heat exchanger 3 exchanges heat between the exhaust pipe 6 and the exhaust gas passing therethrough and the combustion air, and heats the combustion air to a temperature effective for combustion in the combustion chamber. The heat exchanger 3 heats a first intake port 3a that takes in combustion air from the outside air side, and a second intake port 3b that takes in combustion air from the outside air side in order to adjust the temperature of the heated combustion air. And an exhaust port 3l for exhausting the temperature-adjusted combustion air. The combustion air exhausted from the exhaust port 3 l is supplied to the magnetic processing device 4 through the air supply pipe 7.

  Here, both the air on the outside air before being taken into the heat exchanger 3 and the air taken into the heat exchanger 3 and heated are used as the air for combustion in the combustion chamber. It explains using.

  The magnetic processing device 4 includes a combustion air magnetic device 4A that magnetically processes the combustion air heated by the heat exchanger 3, and a fuel magnetic processing device 4B that magnetically processes the fuel sent from the fuel tank 5. The combustion air and fuel magnetically processed by the magnetic processing device 4 are sent to the combustion chamber 2.

  According to this configuration, part of the thermal energy contained in the exhaust gas exhausted after combustion in the combustion chamber 2 is recovered by the heat exchanger 3 into the combustion air, so that the efficiency of heat exchange can be improved. it can.

  Moreover, the 2nd inlet 3b with which the combustion exchanger 3 is provided can adjust the temperature of the combustion air heated excessively by heat exchange to predetermined temperature.

  The configuration shown in FIG. 2 is a configuration example for automatically performing temperature adjustment in the heat exchanger 3 in the configuration shown in FIG. In this configuration example, the combustion improving apparatus 1 of the present invention includes a drive mechanism 3d and a temperature sensor 9 for adjusting the opening amount of the second intake port 3b. The temperature sensor 9 is installed in the magnetic processing device 4, the air supply pipe 7 or the exhaust port 3 l of the heat exchanger 3, and measures the temperature of the combustion air heated by the heat exchanger 3. The drive mechanism 3d captures the detection signal of the temperature sensor 9, and adjusts the opening amount of the second intake port 3b based on the captured detection signal so that the temperature of the combustion air becomes the set temperature. The adjustment of the opening amount can be performed by, for example, driving an opening / closing shutter provided with the second air inlet 3b to adjust the opening degree. Here, the drive mechanism 3d can be configured to include an arithmetic device that calculates the opening amount from the detected temperature, a control device that controls the driving device of the open / close shutter based on the calculated opening amount, and the like.

  The temperature of the exhaust gas passing through the exhaust pipe is, for example, 200 ° C. to 400 ° C., and the heat exchanger 3 can heat the combustion air to, for example, 50 ° C. to 100 ° C.

  Next, a detailed configuration example of the heat exchanger of the present invention will be described with reference to FIGS. 3 and 4, and a detailed configuration example of the magnetic processing apparatus of the present invention will be described with reference to FIGS.

  First, the detailed structural example of the heat exchanger of this invention is demonstrated. In FIG. 3, the heat exchanger 3 can be formed with a double tube structure of an outer tube 3 e and an inner tube 3 f, and the inner tube 3 f can be configured using an exhaust pipe 6. 3A shows the appearance of the heat exchanger 3, and FIG. 3B shows a state where a part of the outer wall of the outer tube of the heat exchanger 3 is cut off.

  A first intake port 3a, a second intake port 3b, and an exhaust port 3l are formed on the outer wall of the outer tube 3e. Further, the outer wall of the inner tube 3f and the inner wall of the outer tube 3e form a flow passage through which combustion air flows by an annular space portion sandwiched between the two walls. The combustion air flows through the flow path from when it is taken in through the first intake port 3a until it is discharged from the exhaust port 3l. During this time, heat is transferred from the exhaust gas through the outer wall of the inner tube 3f and heated. .

  The second intake port 3b is disposed on the downstream side of the first intake port 3a in the flow passage, and takes in combustion air having a low temperature from the outside air. The combustion air taken in from the second intake port 3b reduces the temperature of the combustion air that is excessively heated while flowing through the flow passage. The temperature drop of the combustion air due to the intake of the combustion air from the second intake port 3b can be adjusted by the degree of opening of the second intake port 3b. When the opening / closing shutter 3c is provided in the second intake port 3b, the opening / closing shutter 3c can be adjusted according to the degree of opening of the opening / closing shutter 3c. When the opening / closing shutter 3c is opened largely, the temperature of the combustion air can be greatly reduced. When the opening is small, a decrease in the temperature of the combustion air can be suppressed.

  Furthermore, the heat exchanger 3 of the present invention has a spiral flow path 3h in an annular space portion sandwiched between the outer wall of the inner tube 3f and the inner wall of the outer tube 3e in order to increase the heat transfer efficiency from the exhaust gas to the combustion air. Form. By providing the spiral flow path 3h, the length of the flow path through which the combustion air flows in the annular space can be increased, and the heat transfer efficiency from the exhaust gas to the combustion air can be increased.

  The spiral flow path 3h can be formed by providing a spiral wall 3g between the outer wall of the inner tube 3f and the inner wall of the outer tube 3e.

  The open / close shutter 3c shown in FIG. 3 shows a configuration example that slides, and the open / close shutter 3c shown in FIG. 4 shows a configuration example that rotates. In any configuration, the area of the opening portion of the second intake port is adjusted by moving the open / close shutter 3c. As the drive mechanism for driving the open / close shutter 3c, for example, a solenoid mechanism that linearly reciprocates in the case of a slide operation, or a motor mechanism that can be rotated in a reverse direction in the case of a rotation operation can be used.

  Next, a detailed configuration example of the magnetic processing apparatus will be described with reference to FIGS. FIG. 5 shows a view and a cross-sectional view of the end surface of the magnetic processing apparatus 4, FIG. 6 shows a perspective view of some components of the magnetic processing apparatus 4, FIG. 7 shows a cross-sectional view of the magnetic processing member, FIG. 8 shows a perspective view of a part of the magnetic processing member, and FIG. 9 shows a view of the end surface viewed from one side of the magnetic processing member.

  In FIG. 5, the magnetic processing device 4 includes a combustion air magnetic processing device 4A that performs magnetic processing by passing combustion air through a magnetic field, and a fuel magnetic processing device 4B that performs magnetic processing by passing fuel through the magnetic field. Prepare. FIG. 5A shows an end surface of the magnetic processing apparatus 4, and FIG. 5B shows a cross section of the magnetic processing apparatus 4.

  The combustion air magnetic processing apparatus 4A according to the present invention is configured to include a plurality of magnetic processing members 4a. Combustion air is introduced from one end of the magnetic processing member 4a, and the combustion air is passed through the interior. Pass through the magnetic field and let it flow out from the other end. By adopting a configuration in which a plurality of the magnetic processing members 4a are provided, the area through which combustion air passes through the magnetic field can be widened to increase the efficiency of the magnetic processing.

  FIG. 5A shows a state in which a plurality of magnetic processing members 4a are provided side by side when viewed from one end direction. Here, since the magnetic processing member 4a is formed in a cylindrical shape, when a plurality of the magnetic processing members 4a are provided, the combustion air that has flowed into the magnetic processing device 4 is partially cylindrical. The other part flows through the outer part B of the cylindrical body.

  Furthermore, it is good also as a structure which arrange | positions several this magnetic processing member 4a provided side by side along the direction through which combustion air flows. With this configuration, it is possible to increase the area through which combustion air passes through the magnetic field and increase the efficiency of magnetic processing. Moreover, in this structure, it can be set as the structure which forms a clearance gap between the groups of the magnetic processing members 4a arrange | positioned in the direction through which combustion air flows, and forms the air pool 4h. By providing the air reservoir 4h, the combustion air discharged from the group of the upstream magnetic processing members 4a temporarily stops in the air reservoir 4h.

  In the cylindrical magnetic processing member 4a, since a magnetic field is mainly formed inside, the combustion air flowing inside the cylindrical body A is magnetically processed, but the combustion air flowing outside the cylindrical body B There is a possibility that the magnetic treatment is not sufficiently performed.

  On the other hand, by providing the air reservoir 4h, the combustion air discharged from the group of the magnetic processing members 4a is in the air reservoir 4h, and the combustion air that has flowed through the inside A of the cylindrical body and the cylindrical body Combustion air that has flowed through the interior B of the fuel is mixed. The mixed combustion air flows into the group of magnetic processing members 4a on the downstream side. At this time, a part of the combustion air that has flowed outside the cylindrical body B on the upstream side flows into the inside A of the cylindrical body in the group of the magnetic processing members 4a on the downstream side, and is subjected to magnetic processing.

  Therefore, the efficiency of the magnetic treatment of the combustion air can be increased by the air reservoir 4h provided between the upstream magnetic processing member 4a group and the downstream magnetic processing member 4a group.

  In the configuration shown in FIG. 5B, the air reservoir 4i is provided between the inlet of the magnetic processing device 4 and the group of the upstream magnetic processing members 4a, so that each upstream magnetic processing member 4a is provided. The amount of combustion air inflow is made uniform, and an air reservoir 4j is provided between the outlet of the magnetic processing device 4 and the group of the magnetic processing members 4a on the downstream side, so that each magnet on the downstream side is provided. Combustion air from the processing member 4a is mixed.

  Part of the combustion air mixed in the downstream air reservoir 4j is taken in from the intake port 4k, returned to the upstream air reservoir 4i through the combustion air return path 4p, and returned to the upstream air reservoir 4i. The magnetic treatment is performed through the magnetic treatment member 4a. The flow of combustion air from the intake port 4k through the combustion air return path 4p to the extraction port 4l can be formed by the blower 4m.

  By returning a part of the combustion air through the combustion air return path 4p, a part of the combustion air can be passed through the magnetic processing device 4 a plurality of times, and the magnetic processing efficiency of the combustion air can be improved. At this time, by mixing the combustion air in the downstream air reservoir 4j, it is possible to eliminate the unevenness of the returning combustion air and make it uniform, thereby improving the efficiency of the magnetic treatment of the combustion air.

  The fuel magnetic processing device 4B of the present invention is provided side by side with the combustion air magnetic processing device 4A, and is sent from the fuel tank 5 by the residual heat from the combustion air magnetic processing device 4A heated by the combustion air. The treated fuel is magnetically treated and heated. The heating temperature can be, for example, 30 ° C. to 80 ° C.

  The plurality of magnetic processing members 4a can be supported by the support frame 4g. FIG. 6 is a view for explaining the support of the plurality of magnetic processing members 4a. The support frame 4g supports the attached state by fixing a part of the structure provided in each magnetic processing member 4a. As a structure for supporting, it can be set as the axis | shaft 4o with which the magnetic processing member 4a is provided, for example.

  A detailed configuration example of the magnetic processing member 4a of the present invention will be described with reference to FIGS. In the cross-sectional view shown in FIG. 7, two magnetic processing members 4a provided side by side are shown.

  As shown in the figure, a plurality of disc-shaped magnetic pole plates 4c made of a magnetic material, a plurality of cylindrical permanent magnets 4b, a plurality of covers 4p made of a non-magnetic material, and a plurality of non-magnetic materials are attached to the shaft 4o. A disk-shaped spacer 4d is provided to penetrate therethrough. The attachment to the shaft 4o can be performed by penetrating the shaft 4o in a hole provided in the magnetic pole plate 4c, the permanent magnet 4b, the cover 4p, and the spacer 4d. In addition, two permanent magnets 4b are provided on both sides of the magnetic pole plate 4c, and a spacer 4d is provided between the permanent magnets 4b opposite to the magnetic pole plate 4c side of the two permanent magnets 4b. . The permanent magnet 4b on both sides of the magnetic pole plate 4c has the same magnetic pole on the magnetic pole plate 4c side, and the permanent magnet 4b on both sides of the spacer 4d has the same magnetic pole on the spacer 4d side.

  The bottomed cylindrical cover 4p covers the two permanent magnets 4b, the opening of the cover 4p is located on the magnetic pole plate 4c side, and the bottom of the cover 4p is in contact with the spacer 4d.

  Further, a spiral wire 4e made of a magnetic material is provided outside the magnetic pole plate 4c, the permanent magnet 4b, the cover 4p, and the spacer 4d. The shaft 4o, the magnetic pole plate 4c, the permanent magnet 4b, the cover 4p, the spacer 4d, the spiral wire 4e, and the like constitute the magnetic processing member 4a having a plurality of permanent magnets 4b and having the spiral wire 4e on the outer periphery. The

  The cylindrical housing 4f is provided with a plurality of openings 4n. The opening 4n communicates the inside and outside of the housing 4f and allows combustion air to move from the inside to the outside of the housing 4f or from the outside to the inside.

  In the magnetic processing member 4a, for example, when combustion air is passed from one end of the housing 4f to the other end, the combustion air is magnetized. In this case, the combustion air that has entered the housing 4f from one end of the housing 4f exits from the opposite end. At this time, when the combustion air hits the spiral wire 4e, the flow direction is changed by the spiral wire 4e, and the combustion air flows spirally between the spiral wires 4e. As a result, the distance that the combustion air moves through the magnetic processing member 4a becomes very long, and the magnetic processing member 4a can effectively magnetize the combustion air.

  Further, by making the magnetic poles on the spacer 4d side of the permanent magnets 4c on both sides of the spacer 4d the same, the combustion air can be more effectively magnetized.

  In the present invention, since a plurality of openings 4n are formed in the housing 4f, combustion air can be circulated between the inside A of the housing 4f and the outside B of the housing 4f. Although the magnetization efficiency of the combustion air in the outside B of the housing 4f is low, the magnetization efficiency of the combustion air can be increased by flowing from the outside B into the inside A of the housing 4f through the opening 4n.

  FIG. 8 is a view for explaining the movement of combustion air using the opening 4n in the housing 4f, and FIG. 9 is a view showing an end surface as viewed from one side.

  The combustion air existing inside the housing 4f flows while changing the traveling direction in a spiral manner by the spiral flow path formed by the spiral wire 4e. At this time, since the openings 4n are formed at various locations in the housing 4f, a part of the combustion air inside the housing A passes through the opening 4n and flows out to the outside B of the housing 4f. On the other hand, the combustion air existing on the outer side B of the housing 4f flows while changing the traveling direction due to the flow or vortex of the combustion air flowing out from the inside of the housing 4f. At this time, since the openings 4n are formed at various locations on the housing 4f, a part of the combustion air on the outer side B of the housing 4f flows into the inner side A of the housing 4f through the opening 4n.

  Thereby, even if it is the combustion air which flows the outer side B of the housing 4f, since the opportunity to flow in the inner side A of the housing 4f arises, the magnetization efficiency of the combustion air can be increased.

  As described above, according to the magnetic processing apparatus of the present invention, a configuration in which a plurality of magnetic processing members 4a are arranged in the direction of flow, a configuration in which an air pocket is provided between the two magnetic processing members 4a, and the inside of the magnetic processing device In the configuration, the magnetic efficiency of the combustion air can be increased by a configuration in which a part of the combustion air is returned, a configuration in which a spiral wire is provided and the flow path length of the combustion air is extended. Each of these configurations can increase the magnetic efficiency of the combustion air even by a single configuration.

  The present invention has many embodiments, and various modifications can be made based on the above disclosure. For example, the following are included.

  (1) The number of magnetic processing members may be increased or decreased as necessary.

  (2) The fuel supply from the fuel tank to the magnetic processing device may be configured to be drawn by the magnetic processing device or the pump means provided on the combustion chamber side, in addition to the pumping means provided in the fuel tank. .

Moreover, as fuel, in addition to liquid fuels such as gasoline, light oil, heavy oil, kerosene, and LPG, it is also applicable to gaseous fuels such as city gas.
